Problems solved by technology

[0003] In order to reduce the size of the device, the reactive power compensation modules in the existing low-voltage suppression harmonic reactive power compensation module device are usually fixedly installed together in layers. When the lower reactive power compensation module needs to be repaired, the uppermost reactive power compensation module needs to be disassembled first, and then the lower reactive power compensation module can be repaired, which will lead to increased maintenance and replacement work and repeated disassembly Installation will easily lead to an increase in the failure rate of the device, and it is not convenient for quick maintenance of reactive power compensation modules at all levels. For this reason, we propose a low-voltage suppression harmonic reactive power compensation module device

Embodiment 1

[0036] Example 1: Reference Figure 1-6 The shown low-voltage suppression harmonic reactive power compensation module device includes a bottom box 1 . The bottom box 1 can be any base structure in the prior art, such as a metal box, the first box 4 and the second box 6 are adapted to the position and size of the bottom box 1, and the bottom box 1 The third box body 8 is installed on the inner walls of both sides, and the first box body 4, the second box body 6 and the third box body 8 can be any one in the prior art.

[0037] A reactive power compensation module 9 is installed on one side inner wall of the first box body 4, the second box body 6 and the third box body 8, and a fixed plate 16 and the top side of the fixed plate 16 are installed on one side of the bottom box 1 Rotation is installed with L-shape baffle plate 17, and fixed plate 16 and L-shaped baffle plate 17 can be any one in the prior art, and L-shaped baffle plate 17 is by being used for the expansion mechani...

Embodiment 2

[0043] Embodiment 2: Different from Embodiment 1, in this embodiment, such as Figure 7 As shown, the bottom side of the bottom box 1 is provided with a circular hole, and a crossbeam 21 is installed on both sides of the circular hole, and a heat dissipation fan 22 is installed on the bottom side of the crossbeam 21. The advantage is that when the reactive power compensation module 9 is working, the heat dissipation fan 22 starts, and the heat dissipation fan 22 sucks the air near the bottom side of the bottom box 1 and brings the heat generated by the reactive power compensation module 9 into the gap on the top side of the device. Exhaust, using bottom suction heat dissipation, can suck in the air with lower temperature at a lower position, and make the heated air discharge upwards, thereby improving the efficiency of heat dissipation.

[0044] In this example, if Figure 7 As shown, the bottom side of the bottom box 1 is equipped with a mesh frame body 23, and the mesh fram...

Abstract

The invention discloses a low-voltage harmonic suppression reactive compensation module device, which relates to the field of reactive compensation modules and comprises a bottom box, wherein first box bodies and second box bodies are mounted on one side of the bottom box through two unfolding mechanisms capable of being unfolded in parallel, the two first box bodies and the two second box bodies are matched with the bottom box in position and size, third box bodies are installed on the inner walls of the two sides of the bottom box, and reactive compensation modules are installed on the inner walls of one sides of the first box bodies, the second box bodies and the third box bodies. In the invention, when the reactive power compensation module device needs to be overhauled, the two first box bodies and the two second box bodies are driven to be unfolded in parallel through the unfolding mechanism, so that the reactive power compensation module is separately unfolded, the specific reactive power compensation module is conveniently and independently overhauled, the working intensity is reduced, the failure rate rise caused by repeated disassembly and assembly can be avoided, and the modules are very convenient to maintain.

Description

technical field [0001] The invention relates to the field of reactive power compensation modules, in particular to a low-voltage suppression harmonic reactive power compensation module device. Background technique [0002] Reactive power compensation, full name Reactive power compensation , is a power power supply system middle rise power grid of power factor The role of reducing the loss of power supply transformers and transmission lines, improving power supply efficiency, and improving the technology of power supply environment, especially in low-voltage transmission, the application of low-voltage suppression harmonic reactive power compensation module can reduce the loss of the power grid to the greatest extent, improve the power grid Therefore, it is widely used. The reactive power compensation module device is usually formed by combining multiple reactive power compensation modules according to the power of the grid. [0003] In order to reduce the size of the ...
